Name: Zootrophion serpentinum Luer

Synonyms: Epibator serpentinus (Luer) Luer

Etymology: The genus name Zootrophion is derived from Greek in the sense of “menagerie,” referring to the unusual flowers that resemble small animal heads. The specific epithet serpentinum means “serpentine” and refers to the appearance of the plant.

First description: The species was described by Carlyle A. Luer in 1984 as Zootrophion serpentinum.

Origin/Distribution: Ecuador.

Habitat: The species grows epiphytically in moist cloud forests at an altitude of approximately 1,100–1,950 m. We recommend medium, filtered light, high humidity, and good air movement. Cool-temperate to temperate conditions of approximately 12–23 °C during the day and 8–16 °C at night are favorable. Consistent moisture is important, while the roots should remain well-aerated.

Description and notes: Zootrophion serpentinum is a small-growing Pleurothallidinae orchid with creeping to pendulous shoots and individual leathery leaves. The small flowers have fused sepals, giving them the characteristic closed, animal-head shape of the genus. We cultivate the species in a fine, airy, and slightly moisture-retentive substrate or mounted with some moisture-retaining material at the roots. We water regularly with the softest water possible and do not let the plant dry out completely for extended periods.
